Detailed explanation-1: -What is thermal conductivity? Thermal conductivity is a measurement of a material’s ability to transfer heat energy. Thermal energy transfers from areas of high temperature and molecular agitation to regions of low temperature and agitation. This process occurs until the material reaches a uniform temperature.

Detailed explanation-2: -Conductivity. Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy. Materials are classified as metals, semiconductors, and insulators.

Detailed explanation-3: -Thermal conductivity can be defined as the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area.

Detailed explanation-4: -Example – copper is both malleable and ductile Thermal conductivity-ability of an object to transfer heat Electrical conductivity – ability to carry electric current. Most metals are good thermal AND electrical conductors. Metals also generally have low specific heat (which means they heat up quickly).

Detailed explanation-5: -Thermal conductivity is the measure of ability of a material to conduct heat. Thermal conductivity is a well-tabulated property for a large number of materials and can be found in the different heat transfer or thermodynamics references.
